Title: Electromagnetic clutch control device for vehicle
Inventor: IWAMOTO SHINICHI
IPC: F16H63/46
Filed: 1994-12-27
Abstract: PURPOSE: To cope with clutch sliding which is generated by the initial tolerance of an electromagnetic clutch, secular change, and the like, and also satisfy accelerating property which is intended by a driver so as to obtain stable starting performance at all times. CONSTITUTION: On/off signals in various kinds of switches and pulse signals in various kinds of sensors are inputted in the CPU in an ECU 63, respective clutch currents which are outputted from the ECU 63 flow onto a coil 15 through the feed brush 19 of an electromagnetic clutch 1 so as to control the clutch torque of the electromagnetic clutch 1. In a starting control mode, when a target car speed change amount which is calculated from the accelerating opening degree change amount of an acceleration opening degree sensor 56 accompanying with step-down of an accelerating pedal 54 is not matched with the change amount of real car speed, it is judged that clutch sliding of the electromagnetic clutch 1 is not properly. As a result, clutch current is changed high/low, and a proper clutch torque is applied.

Title: Rectifier provided with input protective function
Inventor: SUGIYAMA TAKAHIRO
IPC: H02H7/125
Filed: 1988-12-23
Abstract: PURPOSE:To keep the output voltage of a circuit below a predetermined level by providing a current source across a coil. CONSTITUTION:Output from a voltage stabilizing circuit 5 is held at a constant level regardless of the output from a rectifying circuit 3. Since the output from a voltage detecting circuit 4 increases monotonously as the output from the rectifying circuit 3 increases, output from a voltage comparator 6 becomes active when the voltage comparator 6 detects the output from the rectifying circuit 3 higher than a predetermined level and thereby a current source 2 functions to feed current across the current source 2. Consequently, load of a coil 1 increases and the voltage across the coil 1 drop. As a result, outputs from the rectifying circuit 3 and voltage detecting circuit 4 drop to invert the output of the voltage comparator 6, and no current flows across the current source 2.

Title: Electric insulation sheet
Inventor: TAKAHASHI KATSUHARU
IPC: H01B3/00
Filed: 1988-12-23
Abstract: PURPOSE:To obtain an electric insulation sheet suited for a substrate for printed circuit boards and having excellent dimensional stability and bending characteristic by using a glass fiber cloth as a base material and epoxy resin of a specified thickness and of two or more functions. CONSTITUTION:An epoxy resin layer 6 of two or more functions and is 10-150mum thick is formed on both surfaces of a base material or a glass fiber cloth 5. When an electric insulation sheet 1 is bent, the stress distribution is such that tensile stresses 3 and compression stresses 4 exist respectively on the convex and concave sides of the center line 2, increasing toward both surfaces. This arrangement is suited for being bent because the glass fiber cloth 5 not suited for being bent is disposed in the center where stresses are small while softer resin layers 6 are disposed on both surfaces. This provides a sheet of dimensional stability and bending characteristic suited for printed circuit boards.

Title: Thermal transfer and image-receiving sheet
Inventor: ONISHI JIRO
IPC: B41M5/50
Filed: 1990-11-29
Abstract: PURPOSE:To obtain an image with improved print density and enhanced resolution by using a thermal transfer technique in the N magnification made which is performed at a higher transport speed for an image-receiving sheet than a transport speed for a thermal transfer sheet, and further using the image- receiving sheet having a finely uneven surface layer consisting of fine particles and a binder on one surface of a base sheet. CONSTITUTION:A thermal transfer sheet is formed with a thermally melting ink layer on the surface of a base film, preferably through a sensitizer layer, using ink consisting of necessary ink materials. An image-receiving sheet consists of a surface layer with a fine unevenness containing fine particles and a binder, at least, on one surface of a base sheet. The recommended fine particle is such as inorganic fine particle of microsilica having an average grain diameter of 0.5 to 10mum. When a thermal transfer technique in the N magnification mode is used, the ink layer is scraped off efficiently by the fine unevenness due to the difference between the relative speeds of the thermal transfer sheet and the image-receiving sheet at the time of data printing. Thus an image obtained demonstrates high print density and superb resolution.

Filed: 1988-12-26
Abstract: PURPOSE:To take a stereo picture where a picture is not duplicated even if it is watched without using glasses, etc., by arranging two filters with different spectral transmittance characteristics at right- and left-handed sides over an optical axis, in the vicinity of a diaphragm. CONSTITUTION:A filter selectively transmitting light of a band exposing the red-sensitive layer of a color film is used for the filter 3a, while a filter selectively transmitting light of a band exposing green- and blue-sensitive layers of the color film is used for the filter 3b. A latent image made of a luminous flux transmitting the filter 3a is recorded on the red-sensitive layer of the color film photographed through the use of this pair of wavelength selective transmitting filters, while a latent image made of a luminous flux transmitting the filter 3b is recorded on the green-sensitive layer and the blue-sensitive layer. Consequently, a viewer watches not a clear duplicated picture, but merely a picture having no unpleasantness, not using glasses, because color slurring is within the defocus range of a photographing lens.
